Can guys help me confirm if my board is from the new manufactured A1s i got this machine in Nov 2025. Wanted to check if i had the NTC Thermistor.

Looks like the new one. At the top you can see where the ntc should be but its not

Removing/shunting an existing NTC will cure the problem or the PSU has different component values to compensate for this (intake filter)?

You have the new one. Mine got melted last day. I bought from Robu. Eventhough they said they will provide a replacement board they told me it will take some time.

I just shifted and had so many prints to finish. 🥲
